This guide for teachers, students, and adults illustrates how it is possible to use Ward's Island as an outdoor laboratory. It contains a guide to 30 kinds of trees on the island, along with clearly drawn maps and illustrations. The guide helps the user to locate these trees along two nature trails. A section called "Ward's Island Roundup" briefly discusses some of the rich history of the island which was once the home of the Merechkawick Indians, sold by the Indians to the Dutch governor of the New Netherlands settlement in 1637, controlled by the British thirty years later and used as a military camp during the Revolutionary War. The islands' flowers, weeds, rocks, natural and man-made geography are described. A section is also devoted to consideration of the island's future. (BC)
